I think Rivers, Ryan, and Dalton would have to accomplish a lot more to get in.
Keep in mind the bar is lower for QB's than LB's and OL.
If Dalton's career ended in a year or 2, not a chance. If he continues to be healthy, and plays into his mid-30's, he is a lock.
Rivers and Ryan are first tier QB's. If they play 3-4 more years, they will hold so many records they will be first ballot HOF.
